COOLING-TUB FOR POWER HAT-SIZING MACHINES.

SPECIFICATION forming part of Letters Patent No. 243,188, dated. June 21, 1881.

Application filed May 19, 1881. (No model.)

To all whom it may concern:

Be it known that I, GEORGE YULE, a citizen of the United States, residing in the city of Newark, county of Essex, and State of New Jersey, have invented certain. new and useful Improvements in Cooling-Tubs for Power Hat- Sizing Machines, fully described and represented in the following specification and the accompanying drawings,forming a part of the same.

My invention relates to an improvement in hat-sizing machines of the class containing several rollers, usually three or four in number, mounted upon a tank of hot water, and provided with a plank or shelf upon which to croze the hats during the felting operation.

It consists in supplying the plank with a cooling-tub sunk below its surface, and in forming an aperture through the body or at the edge of the plank, so that the operator can readily reach the water in the tub.

My invention is designed as a substitute for the pail or tub usually placed upon the top of the plank, or upon some adjacent support, and which is objectionable in practice for the following reasons: If placed upon the plank it is too high to reach with ease, and as the plank is usually inclined toward the machine it is constantly slipping away from the oper-- ator or interfering with his manipulation of the machine by standing in the way. Ifplaced elsewhere the operator cannot reach it without turning his body or making some needless movement, and as it is constantly used to cool his hands when dipping the felts in the scalding .water of the tank, or when rolling them in the cloth upon the plank, it is obvious that his work will be materially facilitated by having a tub of cool water in the most accessible place. Such a place is afforded by sinking the tub below the level of the plank, and supporting it either by a flange resting around the edge of a hole in the plank, or by a shelf secured at a suitable distance below the plank, beneath a notch or hole in the same.

In the drawings I have shown both modes of construction, Figure 1 being an end View of the plank and the side of a three-roller machine to which it is attached. Fig. 2 is aplan of the same, and Fig. 3 a front View of the plank, showing the alternative modes of construction.

A is the frame of the machine, B the rollers, O the frame used to adjust the upper roller, D the plank, and E the hot-water tank.

a is a cooling-tub sunk through a hole in the plank at one side of the operator, and I) a flange at the upper edge of thetub to keep it at a level with the surface of the plank.

S is a shelf supported beneath the plank by brackets or boards 0; and d is a notch cut in the edge of the plank at one side of the operator, to afford the freest access to the pail or tub standing upon the shelf.

By the use of either device the tub is placed in the most accessible spot for the operator to reach, as the opening into the tub is in the surface of the plank itself, upon which his attention is fixed, and he is thus enabled to use the cold water without any loss of time or distraction from the work before him.

By the use of the shelf S any ordinary tub or pail may be used to supply the cold water, while a special vessel is required it fitted to a hole in the plank by a flange, as at 1)..

Having thus shown the essential feature of my invention, I do notlimit myself to the precise means for adapting it to the plank which I have described herein but I claim my invention as follows:

I11 combination with the plank of a powermachine for sizing hats by the operation of rollers, a support for a cooling-tub, and an aperture cut in the plank for the hands of the operator to reach the water, substantially as and for the purpose set forth.

In testimony whereof I have hereunto set my hand in the presence of two subscribing witnesses.

GEORGE YULE. Witnesses:
